La presente invención se relaciona en parte con el sorprendente descubrimiento de que Cry1Da es activo contra el gusano elotero del maíz (DEC), Helicoverpa zea (Boddie). Se describen métodos para usar Cry1Da en plantas transgénicas para prevenir daños graves a los cultivos. Los bioensayos de hojas y seda utilizando maíz transgénico que expresa la región de la toxina central de longitud completa o Cry1Da quimérico demostraron una buena protección contra los insectos contra el daño de las larvas de DEC.

Methods for using Cry1Da in transgenic plants to prevent serious crop damage is described. Leaf and silk bioassays using transgenic maize expressing full length, core toxin region or chimeric Cry1Da demonstrated good insect protection against CEW larvae damage.
